Small UAV parachute recovery system design
Pejchar, Jan ; Jebáček, Ivo (referee) ; Popela, Robert (advisor)
The thesis is focused on the small UAV’s rescue system design. The thesis is divided into related sections reflecting the design process. The first part deals with general problems of parachute equipment. Another part is evaluating critical situations in manual and autonomous control of the airplane. The deceleration device is based on this critical situations as well as the calculated structure loading. Next is the description and evaluation of experiments to verify the performance of modern parachutes. The thesis also includes a simplified proposal ejection mechanism designed in 3D software and documentation of the of model aircraft construction for testing and predicting behaviour in autonomous flight mode.

Passive Safety Features Implementation into Recovery Systems for General Aviation Airplanes
Hájek, Tomáš ; Slavík,, Svatomír (referee) ; Návrat, Tomáš (referee) ; Jebáček, Ivo (advisor)
The thesis is developed in the context of the continuous improvement of safety in personal aviation. The work focuses mainly on small aircrafts, collectively referred to as General Aviation. This thesis aims to evaluate the feasibility of implementing a passive safety feature in the form of an under-fuselage airbag in the rescue systems of small aircraft. The implementation of such a feature will help to reduce the loads transferred to the crew during a rescue parachute landing and effectively reduce the minimum altitude of the ballistic rescue system. This is a new state-of-the-art solution that is unparalleled in its category. The thesis presents a theoretical framework for solving the problem of shock absorption by airbags in the form of a mathematical model. Subsequently, the thesis presents the validation of the mathematical model based on a set of experimental data obtained for this purpose. The theoretical and practical part of the thesis then deals with the elements that influence the airbag performance, namely actively controlled air vent. The last part of the thesis performs a practical design of the implementation of the under-fuselage airbag in the rescue system of a given aircraft in terms of size, location, activation and filling of the airbag. The proposed system is capable of attenuating the impact of the aircraft from a speed of 15 ms-1, thus reducing the application altitude by 10 %. The weight of the newly designed system is equal to 5 % of the total take-off weight. The contribution of the work lies in the combination of two fields of safety that have not been addressed in this category so far, with the distinct result of improving the safety of small aircraft equipped with a ballistic rescue system.

Technical means of aircraft crew rescue
Zemánek, Adam ; Grim, Robert (referee) ; Bartoněk, Jaroslav (advisor)
The aim of this thesis is to create an overview of technical means for rescuing aircrew in emergencies, to compare them within thier categories, and also to create a conceptual design of the activation mechanism for these means. The overview of the means includes the history and current situation of aircrew rescue, using ejection seats and balistics parachute systems. The comparsion of the means is based on their area of application and their characteristics. The conceptual design of the mechanism is designed as a system of pulleys in accordance with the CS-23 regulations issued by the EASA agency. The results of the thesis can expand reader’s knowledge of modern possibilities for aircrew rescue, particuraly in general civil aviation. The developed conceptual mechanism complies with the CS-23 regulations, and it is capable of withstanding the assumed load. Which is confirmed by the conducted strength and stretch testing. Raising public awarness of the rescue systems may ultimately contribute to enhancing safety in aviation.

Amateur first aid knowledge of selected pupils of an elementary school
Fialová, Jitka ; Hanušová, Jaroslava (advisor) ; Kovaříková, Miroslava (referee)
The main goal of this thesis is to analyse the level of amateur first aid knowledge of pupils from grades 6. to 9. at a particular primary school in Dobříš. To achieve this, I utilised partial goals, through which I was trying to find out whether the knowledge of grade 8. pupils of the chosen school was influenced by the fact that there are no lessons taught about theoretical amateur first aid in grade 7. Further, I was trying to establish, if grade 9.pupils have better knowledge of the problem compared to grade 6.pupils; and what grade 9.pupils of the chosen school know about amateur first aid. I was also interested in the fact whether there was any difference in the knowledge of this field between girls and boys. My thesis consists of a theoretical part, in which I researched the given problematic with the help of academic resources, handbooks and other sources. The keystone of the second part, the practical one, is a questionnaire, through which I surveyed the knowledge of the pupils, and then analysed the collected data. The conclusion is made up of general and actual oucomes for subsequent pedagogical application, not only for me, but also for out school.

The role of spontaneous volunteers in the dynamic humanitarian system
Smejkal, Richard ; Pinc, Zdeněk (advisor) ; Sokol, Jan (referee) ; Murgaš, Jaromír (referee)
Increasingly, we hear that the humanitarian system has exhausted its potential and is over the abyss. The volume of funds, the number of humanitarian organizations and the number of rescued people are growing year after year. Nevertheless, the gap between needs and real humanitarian assistance is steadily increasing. Traditional humanitarian actors have been unsuccessfully looking for ways to repair the system that once worked well. Attempts at financial and institutional reform fail, and the debate on humanitarian principles annoys the main actors. This work shows that the traditional humanitarian system is only a part of the larger ecosystem of humanitarian assistance, and analyzes the external influences it fails to cope with in the last decade, and why minor repairs and corrections are not enough and a new system architecture is needed. The author identifies new humanitarian actors with whom the traditional system does not count and points to spontaneous volunteers as a group with dynamic potential and ability to create a parallel system to professional disaster and emergency managers. Since it is an undervalued and overlooked actor, the author refines the definition of spontaneous volunteering. Using the case studies of the Cajun Navy in Louisiana (U.S.) and the confessions of medical rescuers...

Title Scuba diving technical equipment comparison after year 1950 and comparison with rescue units Goals: The main goal of this Bachelor's thesis is to compare the development of a recreational scuba diver's technical equipment after 1950, focusing on the 20th century. The secondary goal is to describe the scuba equipment of an emergency diving unit. Methods: In my Bachelor's thesis, I used both analysis and comparison. I applied the method of analysis in the introduction which consists of an overview of important historical data, personalities which had an impact on the development of scuba diving, and other important data associated with the development of scuba equipment. The main part of the Bachelor's thesis is a comparison of scuba equipment over the individual stages of its development. Results: The significant progress in scuba diving equipment, new materials, and changes in organizational structures seen in the past 50 years have been emphasized in my work.
